More hesitation? Wtf?

***solovus*** · 05-05-2008, 01:44 PM

Ok. So I installed AP on Friday and it cured the slight hesitation and gave the car an obvious boost in power. Well today I noticed the hesitation again so I plugged the AP in and noticed I was only hitting 8psi ... yes I was in S#. So I pull over and check for ECU codes...there are none. I reset the ECU (cleared learned parameters) and BAM! Ok that was weird. Then it happens again. So I reset and it goes away. It is fine right now, but does anyone have a clue as to why my ecu is "learning" to reset boost to 8psi and cause hesitation problems? I mean wtf is going on?!

Ok. Well I reflashed/reset. I didn't even realize how rough the car was idling I reset. Anyways, the power delivery was MUCH better. No hesitation has returned yet, no codes, just pure happiness.

Has anyone else had a similar experience?

Call Cobb and let them know. If the map from Perrin fixed the issue, something is obviously wrong with the Cobb.
